Amazon.com Review
Hitachi's superior design and engineering make this a top-of-the-list choice for a framing nailer, just as hardworking as the NR83 model that preceded it, but with a few major improvements.

We like the way Hitachi's integrated both types of trigger, so there's no need to replace anything – just flip the lever on the tool down for bump or up for sequential firing. Also tool-free is the depth-of-fire adjustment: Just turn a small knob to set your depth. It's even easier than adjusting the air pressure.

This nailer has a 21-degree angled magazine and fires nails from 2 inches to 3-1/2 inches, a wider range than the old NR83 handled. Loading is much faster and easier on this gun, too, because Hitachi's redesign repositioned the loading mechanism at the rear of the magazine. A maximum of 64 plastic-strip collated full round head nails will fit in the magazine, but reloading takes a few seconds, so there's no downside to that. This is one of the most jam-free guns we've used; it just fires and fires. Should you find a way to jam it, the procedure to clear the jam is super fast and couldn't be easier.

The balance of this tool is incredible; at a relatively light 7-1/2 pounds, you'd expect to feel a little strain after using this gun for a few hours, but the ergonomics are fantastic. Hats off to Hitachi on this redesign. And of course, you'll notice immediately the difference in appearance between this gun and its predecessor. It's sporting Hitachi's hot new look, with brighter colors and a flame-like graphic, better suited, we think, to the new personality of this fantastic nailer.--Kris Jensen-Van Heste

Adjustable Depth of Drive for Accuracy
The NR90AE features a convenient depth-of-drive adjustment knob located near the nose. Simply turn the dial half way to make quick, accurate modifications to the driving depth with no tools required.

Quick-Load Magazine for Reduced Downtime
For further convenience, the NR90AE features a lightweight anodized aluminum back-loading magazine that's designed for quick and easy loading of round-head plastic strip nails from two to 3-1/2 inches in length. The magazine has a nail capacity of 64-70 nails, which is equivalent to two nail strips.

By simply sliding the selection control up or down with your hand, you can choose between intermittent and continuous firing. Intermittent firing is ideal for jobs that require precise driving, while the continuous setting can be used to fire nails at a rapid pace by using a bumping motion along the workpiece.

Its soft rubber grip provides optimum control and extended comfort for all-day jobs.For further ease of use, a hardened toenail push lever will help the nailer stand up to wear and tear. And in case you get a jammed nail, the open nose design will make extraction a cinch.

Designed with a 3/8-inch NPT thread air inlet, the NR90AE requires 70-120 psi operating pressure to function properly. It takes in air at a rate of 0.088 cubic feet per cycle at 100 psi.

The Hitachi NR90AE Framing Nailer is backed by a five-year limited warranty.

Customer Reviews

Great Framing Nailer
I have been in the market for a Framing Nailer for two months. Tested a number of units including Porter Cable, Senco, Bostitch, Paslode and more. This Hitachi NR90AE beat them all for weight, balance, easy loading, jam free operation, depth adjustment and trigger selection.
This unit has all the features of the more expensive Hitachi Units, but appears to be lighter weight. As with most nailers, there is no standard case included, and for some reason Hitachi chooses not to include the standard 3/8" NPT connector.
Hitachi has also made a small mistake in its packaging for this tool. Nowhere on the box does it inform you of the angle of the nails used in this nailer. It uses 21 degree plastic collated full-round-head stick nails.

Hitachi rocks!
I bought this nailer to frame and deck a 24x35 shop. It has worked flawlessly without a single misfire while driving a couple thousand nails. I shot 2" - 3 1/2" nails and all fed smoothly and drove in cleanly. The tool-less depth of drive feature is nice, but I found it just as easy to adjust the air pressure depending upon what length nail I was using. It's light and well-balanced. The only problem I had was self inflicted; the nailer fell off a 10' wall and landed square on the rear cover. Afterwards, it would not work, so I disassembled it to find a crack inside the cast aluminum exhaust housing. The replacement was ~$27, but it took two weeks to get in. It's been dropped from the roof and attic space of the shop (12'+) a couple of times since without incident, so I'll chalk the first failure up to bad luck. The repair guy that sold me the replacement exhaust cover informed me that Hitachi was their best performing nailer (they also carry paslode, senco, and one other brand) and he could not give me any negatives. A wish list item for Hitachi would be a "stud hanger" that you could use to hang the nailer on while working above ground. Without one, you're subject to put it in precarious positions and it's subject to fall. :-)

Some nice inovations
I purchased this item recently and have used it for about 4 weeks in a commercial construction environment. It has performed well without problems as anyone would expect of an industrial tool such as this. There are some nice new features over the N83 worth mentioning. 1) The gun load from the rear as opposed the old top loading mechanism. This is faster and can be done with the gun in any position even upside down. 2) The depth adjustment is done with a nob next to the trigger which is new to hitachi and it works well. For those familiar with the Bostich fence nailer it works the same way. 3) The gun can be set to either bounce trigger or single fire. This setting is changed with a small lever just the to the left of the trigger.

Lastly this gun is very quiet compared with others I've used. My only complaint is that it is fairly heavy compared with my Magnesium Framed PC. The tradeoff of course, is that the mag framed guns are not as tough though I had several years of service from it.
